我正在开发一个具有相当简单的web api的小项目。我们决定使用EntitySetController类作为控制器。到目前为止，使用Fiddler2测试web api时所有单词都很棒，我可以使用odata api并在控制器上发出get请求。
下一部分是创建一个简单的客户端来测试代码中的api，所以我创建了一个控制台应用程序，并添加了一个服务引用，并将其指向我的api url。我得到了预期的容器，4个实体类出现在容器下面。问题是2个实体类没有显示使用原始命名空间，2个实体显示。
这是对$ metadata

生成的代理最终出现在：
IRSI.Utilities.Electricity.Model.ElecricityInvoice;
IRSI.Utilities.Water.Model.WaterInvoice;
IRSI.Utilities.Data.Client.UtilitiesService.Concept;
IRSI.Utilities.Data.Client.UtilitiesService.Store;
其中IRSI.Utilities.Data.Client是控制台应用程序的命名空间
，容器是：
IRSI.Utilities.Data.Client.UtilitiesService.UtilitiesContext;
在Web Api我正在设置这样的路线：
public static void Register(HttpConfiguration config)
{
// Web API configuration and services
// Web API routes
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
builder.ContainerName = "UtilitiesContext";
builder.EntitySet<Concept>("Concepts");
builder.EntitySet<Store>("Stores");
builder.EntitySet<ElectricityInvoice>("ElectricityInvoices");
builder.EntitySet<WaterInvoice>("WaterInvoices");
config.Routes.MapODataRoute("odata", "odata", builder.GetEdmModel());
}
我是否遗漏了一些告诉客户以不同方式生成代理的内容。理想情况下，它应该是原始命名空间，如模式中的命名空间。接下来最好是完全使用一个模式，就像服务命名空间下的所有实体一样，但不是2的混合。
